Definitions

  • the present invention relates to the field of mounting axes having axial, radial or angular alignment defects, in particular sensor axes, and relates to a floating mounting device of an axis suitable for this purpose.
  • US-A-3,365,252 an arrangement according to the preamble of claim 1 with a preload bearing assembly allowing misalignment.
  • this document does not disclose that the housing serves as a support for the other elements.
  • the housing shown in this document US-A-3,365,252 is only intended to form a rigid housing for a bearing and to allow the latter to be joined to an elastic element.
  • the object of this patent is intended for preloaded bearings, the elastic element forming a wall of a chamber that can be pressurized.
  • the bearing is preloaded at one of its ends and is mounted in a housing which is connected, by means of a bellows, to an end casing which can be put under a pressure different from the external pressure.
  • This principle of prestressing is not applicable to the resolution of the problem posed in the present invention, namely to allow significant misalignments without harming the operation of the sensor.
  • the present invention aims to overcome these drawbacks.
  • an arrangement comprising: an axle, a cover, and a floating mounting device for the axle, which is constituted by a rigid housing for housing the axle and by an elastically deformable mounting element of the rigid housing in the cover, characterized in that the arrangement comprises an encoder-sensor assembly and the rigid housing serves as a support for the constituent elements of the encoder-sensor assembly, namely the movable elements of the encoder and electrical circuits and sensor electronics.
  • the figure of the appended drawing represents, by way of example, an arrangement comprising: an axis 1, a cover 2, an encoder-sensor assembly and a floating mounting device 3 of axis 1, which is constituted by a rigid housing 4 for housing the axis 1 and by an elastically deformable element 5 for mounting the rigid housing 4 in the cover 2, in which the rigid housing 4 serves as a support for the constituent elements of the encoder-sensor assembly, namely the elements of the encoder and to the electrical and electronic circuits of the sensor.
  • the elastically deformable element 5 is advantageously constituted in the form of a plastic bellows, preferably PTFE.
  • This element 5 is mounted, on the one hand, at one of its ends, by an annular part 5 ′ of smaller diameter than the internal folds of the bellows, on an external bearing 6 of the rigid housing 4 and, on the other hand, at its other end, by an annular part 5 "of larger diameter than the external folds of the bellows, in an internal bearing 7 of the cover 2 of the encoder proper.
  • PTFE a synthetic material such as PTFE as a constituent of element 5 makes it possible to avoid, in certain industries, the effect of an electric battery which can occur when using alloys such as nickel- chrome, PTFE having a perfectly neutral behavior.
  • PTFE allows adaptation to relatively large misalignments between the cover 2 of the encoder and the axis 1.
  • the rigid housing 4 also serves as a support for the constituent elements of the encoder-sensor assembly, namely the mobile elements, as well as for electrical and electronic circuits.
  • This embodiment therefore makes it possible to mount all the elements of a sensor outside the cover, then to carry out the assembly of these elements with the cover 2 by simple insertion into the latter and mounting by means of the elastic element 5. As a result, it is no longer necessary to have a specific installation mounting and adjustment of these various elements with simultaneous maintenance of the cover 2.
  • the device according to the invention is applicable equally to solid or hollow axes without requiring an additional accessory device.
